What
do I need to
know when shopping for jewelry
Quality jewelry is made with gold, platinum, silver
and gemstones such as diamond, ruby, sapphire, emerald, pearls as well
as lab-created gems. Lesser quality jewelry will be made with metal
alloys such as brass, tin, zinc, copper and gemstones which are more
abundant than the precious gemstones above. Jewelry can be expensive if
quality materials are used or not so expensive if lesser materials are
used. Then there are the fake jewelry items often offered for sale but
are essentially worthless. The best way to buy jewelry is to buy
from a trusted source.
GOLD
KARAT:
Pure gold is so
soft it is
rarely
used alone in jewelry. Jewelers deal with various gold alloys,
collectively
called karat gold. Karat (K)
tells the number of parts, by weight, of gold in 24 parts of alloy. The
higher the percentage of pure gold, the higher the karat. Pure gold is
24K. 18K is 18 parts fine gold and 6 parts metal; 14K is 14 parts fine
gold and 10 parts metal; and 10K is 10 parts fine gold and 14 parts
other metal. Anything less than 10K is not considered gold.
GOLD
Gold has the
longest and most storied history of all precious metals. It is soft
enough to be worked into interesting shapes, and its warm color and
scarcity gave it great value in early civilizations. It has been the
foundation of many monetary systems, and remains important to our
economy even today.
As jewelry, it was gold's softness and natural beauty that made it
appealing, in addition to the fact that it doesn't corrode or tarnish.
It is so soft, in fact, that pure gold is rarely used in jewelry. It is
mixed with another metal, usually copper or silver, to make a stronger
gold alloy, or mixture of metals. The quantity of gold in a given alloy
is expressed in karats (abbreviated as K or KT). Pure gold is 24K; 18K
gold is 75% gold and 25% other metals. In other words, each karat is
equal to roughly 4.17% of the total of the alloy.
As the karat weight
drops, the metal becomes more durable but less yellow. Sometimes gold
that is a lower karat weight will be plated in high-karat gold to
enhance the color. This is perfectly acceptable as long as you pay a
fair price. Also keep in mind that gold plating will wear off with time
and your jewelry may need to be re-plated.
When buying gold
jewelry, look for a stamp with a karat mark, the manufacturer's
registered trademark and the country of origin.
WHITE
GOLD
White gold has the
same properties as yellow gold, but it has been mixed with different
metals to give it a white color. Instead of the copper and silver used
in yellow gold, white gold contains such metals as nickel, zinc, or
even platinum. However, white gold should not be confused with
platinum, which is much rarer than gold and hence more valuable.
The karat weight
system used in white gold is the same as that used in yellow gold (see
the "Gold" section on this page). 18K yellow gold and 18K white gold
contain the same proportion of gold; only the remaining 25% of the
alloy is different. Sometimes, white gold is plated with an even whiter
metal, such as rhodium (a very rare member of the platinum family), to
enhance its appearance.
White gold was
developed to give a different look to jewelry. The white color is an
excellent setting for very white diamonds, and when used side by side
with yellow gold, it creates a striking effect. Jewelry using both
white and yellow gold is called "two-tone."
GOLD
TONE
Gold Tone is jewelry that is electro-plated with gold and has no
measurable karat weight, oris gold colored. Provides an expensive look
with a fraction of the cost of real gold.
PLATINUM
The most precious
metal commonly found in jewelry is the silvery-white metal platinum. It
is a relative newcomer to jewelry, having become popular in the past
200 years or so. Like gold, it is rare and heavy, but it is more
durable than gold and is sold in purer form. It is sometimes mixed with
a little bit of iridium and ruthenium, which are similar to platinum
but much rarer, for added strength. Platinum is not sold according to
karat weights. It is stamped PT or plat in the United States to
indicate that it is platinum.
Because of its
purity, platinum is excellent for people who are allergic to other
metals. Its light color also makes it popular. Like white gold, it
makes very white diamonds appear bright.
Platinum has
enjoyed an enormous resurgence in popularity in recent years. It has a
very understated and old-fashioned look that has come back into style,
leading more jewelry designers to work with this metal.
STERLING SILVER
The standard for
sterling silver has remained unchanged since 1300 when Edward I of
England established an early trade practice rule for silversmiths,
decreeing that sterling must consist of 92.5 percent pure silver
alloyed with 7.6 percent copper. The term "sterling" refers to the
composition of the metal, never to the weight of a finished item.
Silver is much more
plentiful than gold; however, silver tends to tarnish, making it less
popular in some forms of jewelry. Like gold, silver is too soft for use
in its pure state and must be combined with other metals for
durability. Jewelry made of silver parts and gold parts must carry dual
designations such as "Sterling and 10K."
SILVER
PLATE
Silver Plate is
electro-plated silver over a base metal and has no measurable karat
weight. Provides an expensive look with a fraction of the cost of
sterling silver.
SILVER
SELECT
Silver Select is
Art Carved’s invention (patent pending). It is more
precious than Sterling Silver, and harder than many tarnish-resistant
metals. Like Sterling Silver, it has a brilliant white shine but has
added Platinum that makes it stronger.
SILVER
TONE
Silver Tone is jewelry that is electro-plated with silver and has no
measurable karat weight, or is silver colored. Provides an expensive
look with a fraction of the cost of sterling silver or white gold.
BRASS
Brass is a mixture,
or alloy, of the base metals copper and zinc. Regular brass is
yellow-gold in color, and "red brass" (which contains a larger amount
of copper) is slightly more reddish in color. In comparison
with precious metals (like sterling silver and gold-fill), brass is
very affordable. Among other base metals, it is less pricey than nickel
silver and slightly more expensive than copper. Certain treatments can
add value, and therefore cost, to brass jewelry. Brass can be mistaken
for gold to the untrained eye. Brass jewelry is much less costly than
gold jewelry but brass is not as substantial or long lasting. Gold
generally weighs twice as much as brass. Over time brass will react
with what it comes into contact with while gold will not. Gold will
remain in its fine condition while brass will tarnish or dull. This is
why brass jewelry costs much less than gold jewelry even though the
look is similar.
COPPER
Copper is a bright
shiny reddish-gold metal that is soft and easily malleable. Copper has
been recorded as being used as far back as 10,000 years ago in many
different artifacts, long before gold was used. Ancient civilizations
used copper as decorative body wear & jewelry, as parts of
weapons, plumbing, cookware, and as mirrors. Today, copper is still
widely used and desiredfor its color and versatility.
PEWTER
Pewter has had many
uses throughout history. Since the Middle Ages pewter hasbeen used for
dishes, utensils and servingware, as well as decorative items such as
sculptures, candlesticks, ornaments and jewelry. Pewter is a soft metal
and easily malleable by hand tools for carving, engraving, or presses
which makes it an excellent choice for detailed jewelry or keepsake
pieces. Like sterling silver, pewter is shiny and bright but does needs
regular cleaning to maintain its luster.
TUNGSTEN
The name of this
metal is Swedish and Danish “tung sten” meaning
“heavy metal”.Tungsten is very heavy with a steel
gray to tin-white color and a lustrous finish.This metal has the
highest melting point, and the most tensile strength of all metals.Due
to the hardness of this metal, the shine is not apt to fade as with
other metals that must be polished. Tungsten also has natural
hypoallergenic properties that make it perfect for use in jewelry
making.
CERTIFIED:
A diamond
certificate is a report that attests to the authenticity of a diamond.
It is a reliable and accurate statement of the diamond’s
identity and grade based on an internationally recognized system.
The grade or
quality of the diamond is based
on carat
weight, color,
clarity
and cut.
These are analyzed by several gemologists who use their experience in
combination with state-of-the-art equipment to produce an accurate
description of the characteristics of the diamond.
GIA
COLOR:
Most Diamonds apear
colorless but actually have slight tones of yellow or brown. The closer
the stone comes to colorless, the more valuable it is. Diamonds are
graded on a color scale ranging from D(colorless) to Z(heavily tinted).
GIA
CLARITY:
It is very common
for diamonds to be formed with slight imperfections. These are known as
"inclusions" and can come in many forms, including tiny white points,
dark dots, or feathery cracks. The fewer inclusions, the more the stone
is worth. A diamond's clarity ranking is determined by the number,
size, type and placement of the inclusions.
DIAMOND TW:
Carat is the term
used to describe the weight of any gemstone, including diamonds.
Although the definition of a carat has changed over time, since 1913
the international standard has been 200 milligrams, or 1/5 of a gram.
Often, jewelers describe carats in 1/4 increments.
In jewelry pieces
with more than one diamond, the carats may be described in terms of
total carat weight (TW). This is the combined total weight of all
the
stones in the piece.
PEARLS
PEARL
SIZE (MM):
Cultured pearls are
sold by diameter, measured in millimeters. In general, larger cultured
pearls are rarer and more costly. Price rises significantly with the
size of a pearl.
PEARL
TYPE:
A pearl is formed
when an irritant, such as sand or a parasite, becomes lodged in the
shell of an oyster. The oyster deposits layers of a semi-translucent
crystalline material called "nacre" around the intruder, where it
builds up in layers like the rings of a tree. This process of building
up can continue for years, resulting in a natural
cultured pearl.
Cultured
pearls have replaced the natural
variety
as a result of cultured pearl
farms that scientifically control the production. The process begins
with a mother-of-pearl bead that is inserted in the living tissue of
the mollusk, which in turn coats the bead with nacre. A cultured pearl
is produced in one to three years.
Freshwater
Cultured Pearls are cultivated
in a freshwater mollusk from a lake, river or pond.
WATCHES
MOVEMENT:
Quartz:
Watches use a quartz crystal for time measurement and a battery for
power. They require no winding.
Kinetic
Quartz: Kinetic quartz is
exclusive technology to Seiko. It is a quartz watch without a battery.
The Kinetic quartz generates electrical energy to power itself from the
natural movement of the wearer's arm and wrist. It stores the energy in
a capacitor. The reserve energy lasts 3 to 14 days in a motionless
watch.
Solar
Quartz: Watches use a quartz
crystal for time measurement. Any light source is absorbed through the
crystal and dial. A solar cell converts the light into energy to power
the watch.
SIMULATED
BIRTHSTONES
From the time
gemstones were discovered, they were believed to have mystical powers
and attributes that could be passed to the wearer. The red of ruby was
fiery and passionate; cool blue sapphire was calm and composed. About
2,000 years ago, writers began pairing each of the stones and their
attributes with the months of the year and the signs of the Zodiac, and
with time, the mythology of birthstones evolved. People were expected
to share the attributes of the stone related to their sign of the
Zodiac or month of birth.

AGATE
Agate is a
semi-precious gemstone which is classified as a banded chalcedony or
micro-crystalline quartz. The individual bands or layers give this
gemstone its uniqueness and character.
The layered agate
material that is used in producing agate cameo gem carvings is usually
cut from agates with even parallel layers, a lighter layer above a
darker one. The agate used in today’s cameos is naturally
multiple shades of gray in color, ranging from a milky white
translucent to dark gray. The lower and softer layer is dyed to produce
the highly desirable blue chalcedony color; while the lighter colored
upper layer which is harder does not accept dying and remains white or
milky in appearance.
Only two percent of
all agate material mined is of a quality suitable for detailed cameo
cutting. It is important to note that of this small percentage an even
smaller percentage can be dyed blue making the enclosed cameos precious
and rare.
The exquisite
motifs and silhouettes featured in our cameo offering have been carved
relief style, employing the use of a highly sophisticated ultrasonic
etching process and elegantly framed in karat gold.
ALEXANDRITE
Discovered in
Russia in the early 1800s, alexandrite is named for Tsar Alexander II
and was the national gemstone of tsarist Russia. With an ability to
change its color from green to red depending on the light source,
alexandrite is a very unique and beautiful gemstone. A Mohs' hardness
rating of 8.5 makes alexandrite a very durable and trouble-free
gemstone.
AMETHYST
Amethyst was a
valuable gem until the discovery of large deposits in South America in
the late 1800s; Brazil is the primary exporter to this day, although it
is common in many countries. Still, its deep and attractive color makes
it extremely popular. Banding - darker and lighter zones of color - is
quite common. A good amethyst will be very clear, and the deeper the
color, the better. The most common enhancements are heat and
irradiation. Try not to expose an amethyst to excessive amounts of
bright sunlight, as this can fade its color.
Perhaps the most
unusual magical power ascribed to the amethyst is its ability to
prevent drunkenness. It also is supposed to bring peace of mind to the
wearer, and if properly carved, prevent fatal poisoning. In some
legends, it represented piety and dignity.
Amethyst is the
birthstone for February.
AQUAMARINE
Although aquamarine
comes in many colors, the most prized is a rich, clear, watery blue.
Fairly large and clear aquamarines with good color are among the more
valuable semi-precious gems. They are often given step cuts, also known
as "emerald" cuts, much like aquamarine's mineral sister, emerald. Good
clarity is important in these stones, especially lighter ones where
flaws will be more visible. Brazil is the primary source of aquamarine,
although it is mined in other places as well.
Aquamarine has long
been a positive stone according to legend, bringing with it health,
hopefulness and youth. It was traditionally a favorite of sailors, and
is said to be a good choice for anyone who loves the sea. It could also
bring love and affection if worn properly. Its supernatural powers were
remarkable; legend has it that a person with an aquamarine in his or
her mouth could summon the devil and get questions answered.
Aquamarine is
March's birthstone.
BLUE
TOPAZ
Topaz, and
especially blue topaz, has grown in popularity over the years. The
"pure" topaz color is yellow, and was often confused with chrysolite,
the yellow variety of peridot. However, the use of distinct colors has
helped topaz come into its own. Blue topaz in particular is popular in
jewelry today. It has a watery blue similar to aquamarine, but often
without the green overtones, and its hardness and good clarity make it
an excellent gem. The blue color is often enhanced through
heat-treatment and irradiation.
Topaz was believed
to have incredible medicinal powers in the Middle Ages, even against
the plague. For a healthy individual, it brought about a pleasant
disposition and patience and was a symbol of fidelity and love.
CEYLON SAPPHIRE
Genuine sapphires,
including Ceylon sapphires are part of the Corundum gem family and are
second only to diamonds in hardness. This strength makes them an
excellent choice of jewelry because of their durability.
Ceylon sapphires
are mined primarily in Sri Lanka (formerly Ceylon). The sapphires mined
in Sri Lanka are known for the unique color they produce. Because
Ceylon sapphires occur naturally, the color of the stone varies.
Colors range from
very pale blue to the most vibrant, almost electric blue hue. Our
collection of genuine Ceylon sapphires has been chosen from the middle
of the color spectrum, capturing the heart of the color in its
lustrous, soft blue color, with just a hint of lavender. This
collection has been designed exclusively for Zales.
Often, sapphires
used in jewelry are heat-treated or given chemical diffusion to enhance
their color, these enhancements are permanent.
Sapphire is the
birthstone of September.
CITRINE
Citrine is a clear
yellow form of quartz and is often confused with yellow topaz; citrine,
however, is more abundant. Because of its abundance, there are plenty
of fairly large, clear stones available for jewelry. Clarity and a rich
yellow color are keys to look for in a citrine. It has some of the same
characteristics as amethyst, such as alternating bands of lighter and
darker color, but these bands are harder to see in citrine. Citrine
often comes from Brazil.
Citrine is a
cheerful gem. Its powers are said to include making its wearer
lighthearted, bringing cheerfulness in tough times and offering hope.
It was also believed to help relax people and expel impurities from the
body. People who wore citrine could expect to look healthy and feel
happy.
Citrine is the
birthstone for November.
CRYSTAL
Crystal is created
using a combination of silica (quartz sand) and natural minerals. To
avoid stress and inclusions, the glass is cooled slowly.
DIAMOND
Every diamond is
different, incorporating a complex constellation of factors that
determine the rarity of each stone. Although gemologists train for
years to master the art and science of diamond appraisal, with a little
basic instruction, anyone can learn how to read an appraisal and
compare the grades of different stones.
Each diamond is as
unique as the person who owns it. Just as a diamond reflects the color
of the light it bears, it should also reflect the personality of the
individual who wears it. Here lies the art of selecting a diamond, for
yourself or as a gift.
Truly flawless
diamonds are very rare, and very expensive, so you will seldom face the
task of selecting a perfect diamond. It is a fairly simple matter to
find beautiful diamonds with no flaws visible to the naked eye and buy
them at reasonable prices.
Diamonds are graded
using a system that judges the stone on its color, clarity, cut and
carat weight - commonly known as the "four C's." Diamonds of uncommonly
high quality and size are often sold as "certified diamonds" and come
with a certificate that proves the stone's value. Even non-certified
diamonds, however, should be evaluated using the four C's to help
determine cost.
In this section,
you will learn what each of the C's means and how it affects the value
of the diamond. Although it takes a trained eye to actually see the
qualities described here, knowing what they mean can help you make a
good choice in selecting your diamond.
EMERALD
Emerald is one of
the most valuable gems on the market. The brilliant green of a fine
emerald is unmatched by any other stone, and the extreme rarity of
top-quality emeralds - the most prized emeralds come from just a
handful of mines in Columbia - make it fairly costly. However, there
are supplies of emeralds coming out of other mines.
Almost all emeralds
have inclusions in them; the fewer these impurities, the rarer and
costlier the stone. Because of these inclusions, emeralds can be
brittle, so protect your emeralds from hard contact when you wear them.
Ultrasonic cleaners, which use vibrations to remove dirt and buildup,
can be dangerous to heavily included emeralds. Natural emeralds also
tend to have thin scratches on the surface. A layer of wax or oil is
usually applied to smooth out their appearance and enhance their color.
This layer may have to be replaced professionally every few years.
It was believed to
sharpen wits, bring wealth, foretell the future, tell whether a lover
was lying and cure all types of evil and illness.
Emerald is the
birthstone of May.
GARNET
While garnet is
often viewed as a ruby substitute, it has its own unique qualities that
can be appreciated on their own. It comes in a variety of colors,
including many shades of red, from very pale to brick to a red-black.
It comes in larger sizes, usually has good clarity and has a
respectable hardness that allows it to wear well.
Like many red
stones, garnet was once believed to stop bleeding. It was a symbol of
loyalty and energy, promoted sincerity, and was said to have
illuminative powers, both physically and spiritually. Garnet was also
said to alleviate anger, promote tranquility and offer protection in
health and travel.
Garnet is the
birthstone of January.
IOLITE
The name iolite
comes from the Greek ios, which means violet. Iolite is sometimes known
as "water sapphire" because of its light violet blue color, but other
iolite gemstones may range from clear to honey yellow.
The ability of
iolite to exhibit different colors depending on how it is cut is what
led Viking explorers to use it for navigation as a polarizing lens to
look directly at the sun.
JADE
Originally prized
for its toughness and used in tools and weapons by prehistoric man,
jade has a varied history. This gem has been known as the "royal gem"
in China for 5000 years, and it was once valued more than gold by the
Mayans and Aztecs. The name "jade" is derived from the Spanish "piedra
de ijada" or loin-stone where it was thought to have medicinal powers
to heal kidney ailments.
Jadeite and
nephrite are two different minerals that are both considered genuine
jade. Nephrite is the more common of the two and may range in color
from dark green to grey-green. In some instances it can also be white,
reddish or yellowish. Jadeite, which is rarer, is usually green but
also includes white, pink, red, violet, black and brown hues. It's
normal for jade to contain streaks and other blemishes. These are not
necessarily considered flaws, and in fact some of the patterns created
are considered to add value to a piece.
LEMON
QUARTZ
Quartz is one of
the most versatile gemstones on earth. Many people do not know that
some of the most popular gems such as Citrine, Amethyst, Onyx and
Chalcedony are varieties of quartz.
Quartz has a long
history in the gem and jewelry world. The word
“Quartz” comes from the Greek word krustallos,
meaning ice, because it was believed that quartz was ice formed by the
gods. Throughout history varieties of quartz have been used in place of
the more expensive gems like yellow sapphire, yellow diamond, and even
jade.
Light citrus shaded
quartz, called lemon quartz is a very sunny and bright stone. It is
very fashionable and coordinates well with pastel colors and stones
such as blue topaz and peridot.
Since most quartz
has been heated to enhance its color, the stones should be kept away
from prolonged exposure to strong light or heat.
MOTHER OF PEARL
Mother of pearl is
the iridescent internal layer of mollusk shells and is composed of the
same material as pearls. Though technically not a gemstone, mother of
pearl is used in all types of jewelry from mother of pearl watch faces
to mother of pearl fashion jewelry.
MYSTIC
FIRE
Mystic Fire Topaz
is a colorless topaz that is enhanced with a patented Azotic Coating
producing a permanent and stable blue-green appearance with a rainbow
of color accents. The Mystic Fire Topaz is similar to the rainbow topaz
but is enhanced in a completely different manner. Mystic Fire Topaz is
not found in nature.
ONYX
Onyx is part of the
chalcedony family of colored quartz, which includes agate, cornelian
and jasper. The striking black and crisp lines of onyx makes it
especially popular for jewelry. Because the lines can form in many
different ways, each piece of onyx has a unique appearance. Onyx is
also popular for cameos - when an image is carved into onyx, the color
of the next band shows through. Onyx is opaque, meaning no light shines
through it. Therefore, it is usually cut into a smooth, rounded,
polished dome called a cabochon.
Onyx has a variety
of myths associated with it. On one hand, it was supposed to drive away
evil and high tempers. On the other, it was said to cool the passions
of love and promote independence between lovers - which can be good or
bad, depending on one's point of view. Some people even believed it was
a symbol of discord, a belief probably suggested by the sharply divided
lines in the stone.
OPAL
Opal is made of the
same ingredients as quartz, except it contains a little water and has
not been compressed into crystals. As a result, it is softer than
quartz and has to be treated a little more carefully to avoid damage.
The shifting colors seen in opal, called "fire," are the result of
microscopic spherical structures within the stone which reflect
different wavelengths of light depending on their spacing, creating the
colorful shimmering effect. There is no other gemstone that looks
remotely like it. It comes in both black and white varieties, with
black being the most rare. Australia is the principal source of opal
today. Like other non-transparent stones, it is usually cut into a
smooth, rounded, polished dome called a cabochon.
Some legends say
that opal is good for the eyes, both improving vision and warding off
eye troubles. It also has a reputation for sharpening the mind and the
emotions. Opal is a symbol of fidelity, but it came with a price, since
it would bring trouble to someone who was unfaithful.
Opal is October's
birthstone.
PERIDOT
Peridot is an
ancient stone, mined at least as long ago as the ancient Greeks.
Peridot is also often called chrysolite or olivine, which is the proper
name for the mineral. Its color is its most important quality, and can
range from yellow green to a striking chartreuse. (The chrysolite name,
in fact, often refers to peridot that is more yellow than green.) The
stones have good clarity and are appropriate for faceted cuts since
light sparkles through them. They are relatively soft and should be
protected from abuse.
Peridot offered
protection from depression and deception in Roman times, was used for
inspiration and eloquence in the Middle Ages, and was also used to cure
liver disease and promote friendship. In general, it was believed to
ensure good thoughts in the mind of the wearer.
Peridot is the
birthstone of August.
RHODOLITE
Derived from the
Greek words rhodon and lithos meaning "rose stone", rhodolite is a type
of garnet that varies in color from red-violet to a rich pink-red.
RUBY
Along with the
emerald and sapphire, ruby is one of the most prized colored gem
available. The main quality of the ruby is its bright red color. The
best color usually comes from Burma and is very costly; stones from
Thailand are darker but clearer and much more common. Only red stones
are called rubies. If the color is too light to be called red, it is a
pink sapphire.
Corundum, the main
material of ruby, is the second-hardest material known after diamond.
Inclusions and flaws are fairly common, and many rubies are treated to
enhance their color. In general, one should look for a bright red stone
with as few inclusions as possible. Synthetic rubies offer good color,
clarity and size, and are more affordable.
Rubies were the
most valuable gems in ancient Southeast Asia, where they are found. A
fine ruby had all sorts of magical powers. Its color was thought to
come from an undying flame inside the stone - or, in some legends, a
piece of the planet Mars - and it allowed its owner to live in safety,
even in the midst of enemies. It was believed to bring its owner all
kinds of protection and to stop bleeding. In Burma, it could make one
invincible - as long as it was embedded in the skin. In more modern
times, rubies became the symbol of love and passion.
Ruby is July's
birthstone.
SAPPHIRE
Any color of
corundum except red is called "sapphire," although cornflower blue is
the most popular and sought-after sapphire color. Sapphire comes from
the same places and in the same qualities as its sister stone, ruby,
with the best color coming from Kashmir and Burma. The name "sapphire"
alone refers to the blue variety. All other colors have the color name
added to the stone, as in "orange sapphire," "pink sapphire" etc.
Sapphire often has
some inclusions, but clarity is still quite good. Its base material,
corundum, is the second hardest in existence and so wears very well.
Often, the sapphires used in jewelry are heat-treated or given chemical
diffusion to enhance their color; these enhancements are permanent.
Like rubies and emeralds, there are good synthetics available for
people who like the color but not the cost.
Sapphire is said to
be a mind-opening gem. It is supposed to relax the wearer and clarify
thought, as well as attract "divine favor." On a personal level, it
prevents envy and fraud, and brings truth and good health. It also was
said to be a powerful antidote for poison.
Sapphire is the
birthstone of September.
TANZANITE
While zoisite has
been known for some time, gem-quality zoisite wasn't found until 1967,
when a deposit was uncovered in Tanzania. This is still the only source
for tanzanite, one of the most recent additions to the gem world. It
gained almost immediate popularity both for its scarcity and its rich,
blue-violet color. It is often heat-treated to bring out a uniform
color. While a prized stone, caution should be used when it is worn in
rings, since it is fairly soft and can be scratched or chipped.
Although it usually has good clarity, tanzanite can be damaged by
ultrasonic cleaners, so other cleaning methods are recommended.
Needless to say, as
a recently discovered stone, tanzanite has no ancient legends
associated with it.
TIGER'S
EYE
The unique
appearance of tiger's eye is caused by fibrous inclusions of
crocidolite that have been replaced by silica. Light is refracted off
of these inclusions giving tiger's eye its chatoyancy (changeable
luster).
TOPAZ
Topaz, and
especially blue topaz, has grown in popularity over the years. The
"pure" topaz color is yellow, and was often confused with chrysolite,
the yellow variety of peridot. However, the use of distinct colors has
helped topaz come into its own. Blue topaz in particular is popular in
jewelry today. It has a watery blue similar to aquamarine, but often
without the green overtones, and its hardness and good clarity make it
an excellent gem. The blue color is often enhanced through
heat-treatment and irradiation.
Topaz was believed
to have incredible medicinal powers in the Middle Ages, even against
the plague. For a healthy individual, it brought about a pleasant
disposition and patience and was a symbol of fidelity and love.
Blue topaz is
December's birthstone.
TOURMALINE
The name tourmaline
derives from the Singhalese word "turamali" meaning gemstone. Known as
the "Rainbow Gemstone", tourmaline comes in every color of the rainbow
and most tourmaline gemstones are multi-colored. Gem cutters focus on
bringing out the deepest color when cutting tourmaline. Still, when
viewed from different angles a tourmaline may exhibit several different
colors.
Tourmaline is
reputed to have a powerful positive influence on love and friendship.
With a Mohs' hardness rating of 7 to 7.5, tourmaline is a very durable
and easy to maintain gemstone perfect for everyday wear.
TITANIUM
